1.1 Overview
Through 2016, EPCOR Water Services Inc. (EWSI) continued to satisfy all water
demand requirements while meeting our strict water quality criteria. Despite
growth of the service population, total demand in 2016 fell as compared to 2015
due to the cooler, wetter summer conditions. Residential per capita and total per
capita values also continued to trend downward primarily due to the installation of
water efficient fixtures and appliances. Rossdale WTP and E.L. Smith WTP were
converted from Direct Filtration (DF) to conventional treatment on February 29th
and March 3rd respectively to prepare for the spring runoff. It arrived earlier than
previous years but was short-lived and very mild. The spring runoff did not bring
any taste and odour concerns and required far less chemicals to treat, as
compared to previous years. Mountain runoff, which normally hits the North
Saskatchewan River (NSR) in Edmonton in June and usually brings high
turbidity, was also very mild. The heavy rainfalls in July did increase the river raw
water turbidity to ~1700 NTU and colour to ~40 TCU but the water plants were
able to treat the river water quality easily. Near the end of August, significant
storm events upstream of Edmonton caused the NSR level to rise almost 4
meters in less than a day, bringing high turbidity ~3000 NTU and unusually high
colour of greater than 200 TCU. This high river level event caused a considerable
amount of damage within one of the pumphouses at E.L. Smith WTP. Both water
treatment plants struggled to produce water during this event and demand
management measures were implemented for four days due to low reservoir
levels.
Edmonton WTPs continued to focus on optimizing chemical dosing and
minimizing release of water treatment plant solid residuals to the NSR. Several
process initiatives were investigated to improve plant performance during DF and
solids reduction:
• Higher dosages of filter polymer of up to 2 mg/L were tested in the plants
during DF operation. Zeta potential and filter performance were monitored
during this time in an attempt to optimize filter polymer dose.
• A plant trial was carried out at E.L. Smith for the second consecutive year
during which sulphuric acid was injected into one of the raw water lines to
reduce clarifier influent pH. The objective of the trial was to determine if
pH reduction through the clarifiers would improve filter performance during
the early fall period when raw water pH is relatively high.
• A pilot plant trial was conducted for an alternate filter polymer (LT-7995) in
an effort to improve filter run times and filter effluent quality during direct
filtration.
Conversion from conventional treatment to DF was delayed for both plants due to
the unusually high colour in the NSR that arrived with the high river level in late
August and lasted until the end of 2016. Rossdale WTP converted to DF on
December 19th. E.L. Smith WTP converted Clarifier 3 and Stage 1 filters to DF on
November 28th to accommodate the pH adjustment trial, but was converted back
to conventional treatment on December 3rd due to river water quality. The full E.L.
Smith WTP was converted to DF on December 28th, but was converted back to
conventional treatment on December 30th due to low water production and high
process losses in DF mode. E.L. Smith WTP successfully converted to DF on
January 6, 2017. Despite the challenges, the WTPs were still able to reduce total
solids discharged to the NSR by 41% during the months of January – February
2016 compared to baseline conventional operation. In-stream sampling and
monitoring of WTPs clarifier waste stream discharges to NSR continued in 2016
to further understand the impacts of residuals discharge on the river
environment.
There were a total of four AEP approval contraventions at the WTPs in 2016, as
detailed in Section 1.4 Summary of Violations and Notifications. WTPs continue
to improve the integrated safety and environmental management system in
accordance with the ISO14001:2004 and OHSAS 18001:2007 standards.
Surveillance audits were conducted in late November 2016 for Rossdale and E.L.
Smith WTPs, along with the reservoir sites.
EWSI continued to upgrade the water treatment plants and the reservoir assets.
Thirty-four capital projects under different programs were initiated in 2016 with a
total spending of approximately $13.1M. Some of the major projects are as
follows:
• Rossdale Polymer System Upgrade – construction was commissioned and
completed by Q2 2016;
• Rossdale Chem spill upgrade – construction in progress, plan to be
commissioned and completed by Q2 of 2017;
• ROS - Filter Underdrain Upgrades (Filter# 9) – construction in progress, plan
to be commissioned and completed by Q2 of 2017;
• ROS - Guardhouse and Fence – construction in progress, plan to be
commissioned and completed by Q3 of 2017;
• ELS Lowlift PH Intake Upgrade/ Travelling water screens upgrade –
construction was commissioned and completed by Q4 2016;
• Construction completed for the two new booster stations – Big Lake in the
NW and Walker in the SE. Both sites are commissioned and working on
addressing all deficiencies.
In 2016, Water Distribution and Transmission repaired 242 water main breaks on
the distribution system in Edmonton, with the majority of main breaks occurring
on cast iron pipes. While this number is the lowest number of main breaks
experienced since 1961, the trend of a higher proportion of breaks occurring on
larger diameter mains continued. The general trend of decrease in water main
break activity continued and this improvement in overall reliability of the water
distribution system can be attributed to the water main replacement programs as
well as the use of more reliable pipe materials in both replacement and new
water main construction.
In 2016, the Uni-Directional Flushing program completed flushing and valve
exercising in about 33% of Edmonton (2,112 runs).This program is a five-year
cycle with area prioritization emphasis placed on water quality parameters,
percentage of Cast Iron Mains, and the relative success of the previous flush.
The transmission valve inspection program is ongoing. Water Distribution and
Transmission Customer Satisfaction index year-end results were 77.8% and
finished above the 74% target.
EWSI continues to provide water and wastewater services and expertise to
numerous communities in Alberta, British Columbia, Regina, as well as industrial
sites in Fort McMurray.
As we move into 2017, we will continue to focus our efforts on the production of
and distribution of high quality water, customer satisfaction, protection of the
environment, workplace safety and cost effectiveness. We will continue to ensure
our customers receive best value for the services we provide them. More detail
on our progress towards meeting our EnviroVista Stewardship community will be
included in our annual EnviroVista report, which will uploaded to epcor.com by
June 30th, 2017.

PH-00448
A water sample collected on January 22, 2016 from the E.L. Smith reservoir tested positive for E. coli. Resamples from the same reservoir and from distribution samples on January 23 were all negative for Total Coliforms and E. coli. Identification of bacteria in the E. coli positive sample suggest that it was a raw water sample, that is, the employee erroneously filled the Res Out sample bottle with raw water. It was determined that a sampling error occurred where the sample was erroneously taken from the raw water tap and labeled as a treated water sample from the reservoir.

A sample as part of the random distribution monitoring program tested positive for total coliforms. Following AEP’s Protocol for Failed Bacteriological Results, we attempted to collect a set of four resamples - upstream, downstream and two at the original site. The collection of the first set of resamples happened on Sunday and we were not able to access the business location as it was closed. On this day only three samples were collected (upstream, downstream, and at the nearby fire hydrant). All had chlorine and turbidity within normal operating ranges and all bacteriological results were negative for total coliform and E. coli. The following day (Monday), two more samples were collected from the business itself, one at the original sampling point, and one at an alternate point. Both samples had chlorine and turbidity within normal operating ranges and all bacteriological results were negative for total coliform and E. coli.

As per AEP Approval 638-03-00, Schedule 3, E.L. Smith WTP is to provide continuous monitoring on filter turbidity. On June 1st, 2016, filter 18 NTU meter was flushed and after the flush the meter went to 0.01 NTU and stayed there until the filter was shut off on June 2nd @ 03:40 am. At 15:45 Filter 18 was brought back "On-line", but the NTU meter remained @ 0.01 NTU even though the filter particle counter did spike as per normal during "Filter to Waste". No check turbidity meter alarm came up on SCADA. The filter remained on-line and on June 4th @ 00:54, an Operator checked the meter and the meter then started to respond again. Hourly filter effluent turbidity grab samples were not taken during the period the analyzer was not responding as per Operations Program and Approval requirements. The maximum filter effluent average Particle count during this period did not exceed 12 c/ml. The maximum reservoir influent NTU was 0.04 during this period. Production from filter 18 on the first occurrence was 8 ML. On the second occurrence it was 30 ML.

PH-00522
Drinking water did not meet the minimum requirement for percent Ultraviolet transmittance (UVT) for the UV disinfection system at the E.L. Smith water treatment plant, and was pumped into the finished water reservoir and distribution system for several hours. To prevent depletion of reservoir storage to critical levels by the morning of August 25, the E. L. Smith production was diverted to finished water reservoirs and distribution system with the percent UVT at approximately 87%. Minimum requirement is 88%. At the time of the incident, the quality of the raw water supply in the North Saskatchewan River had deteriorated significantly due to an intensive rainstorm event upstream in the watershed in the days prior to the incident.

Water distribution sample taken at convenience store as part of routine distribution sampling program tested positive for Total Coliforms. Chlorine and turbidity levels were normal. Four resamples were collected as per the AEP Protocol for Failed Bacteriological Results. Chlorine and turbidity were all within normal operating ranges. Total Coliform and E. coli were negative. It was suspected that the normal disinfection procedure that was followed was not sufficient to remove levels of contamination that the utility tap might have had.

After a lead service renewal a sample was taken from a kitchen tap. The aerator could not be removed without a tool, so a sample was taken with it on. This resulted in a Total Coliform Positive. Resamples were collected as per the AEP Protocol for Failed Bacteriological Results. Chlorine and turbidity were all within normal operating ranges. Total Coliform and E. coli were negative for the resample. During the re-sampling event, the aerator was removed, and debris was cleaned from the kitchen tap. The resample at this location was negative for Total Coliform.

On August 16, 1:30 pm, as per routine operational practice every quarter, a sample was taken from the clarifier blowdown at the E.L. Smith Water Treatment Plant for testing. Every quarter, a sample is collected of clarifier blowdown (which is river solids coagulated with alum) and tested by an external laboratory. This practice goes beyond approval requirements. This event was reported as a notification only to Alberta Environment and Parks on September 15th, 2016. During mid-August, very heavy rains in the upstream NSR basin resulted in the NSR having very high flows (peaked at 1,400 cms) and also extremely high suspended solids concentrations and turbidity levels. In operating the E.L. Smith plant to produce potable water it was necessary to use relatively high alum doses to ensure public health protection and the clarifier blowdown was measured to have TSS concentrations. This waste stream is discharged to the river using an in-stream, mid-channel diffuser which uses in-stream mixing for rapid dilution to avoid in-stream adverse effects on biota. The sample collected did exhibit in the laboratory rainbow trout some affects at undiluted strength. At dilutions that the diffuser would achieve in the river no fish populations would have been expected to be affected.

A city of Edmonton crew repairing a sanitary service line for an apartment hit a water service line. EPCOR was contacted and closed the water service, then hooked up temporary water service during repairs. The EPCOR crew used the same temporary adapter in the repair trench to obtain a water sample which tested positive for Total Coliforms and E. Coli, likely from contamination on the outside of the adapter. Chlorine was within normal range. Resamples collected from two locations at the original address and from upstream and downstream were all negative for Total Coliforms, E. Coli and had normal Chlorine residual and turbidity. The distribution system would have been at very low risk for contamination as the water service line had continuous flow and pressure.

Following a complaint of poor quality water EPCOR found low chlorine residual and high turbidity. Total Coliform and E. Coli were negative. Approval to Operate requires 75% of resamples within a 24 hour period be equal to or greater than 0.5 mg/L for chlorine. EPCOR crews were not able to obtain the required 4 samples in the area within 24 hours. The area is a single feed main with only 4 single family residences beyond the last hydrant. The area has low water demand causing the original low chlorine. EPCOR was not able to gain access to all the residences within the 24 hours to complete the required sampling. Resamples were collected after 24 hours, these were negative for Total Coliforms, E. Coli and had chlorine and turbidity within normal ranges.

Customer complaint of Taste and Odor on October 1st from a residence that had been vacant for several months. We initially advised them to flush all taps in the residence. Customer called back on October 7th with a similar concern. A sample on October 7th was collected at in the kitchen from a pull-out spray head, as this was the location of the continued water quality concern. The spray head was not properly disinfected prior to sampling and resulted in a Total Coliform positive. Four resamples, including one at the same spray were obtained. The spray head was Total Coliform positive a second time. All samples were normal for chlorine and turbidity in both sets. A second EPCOR crew was dispatched to the location. This time the spray head was disassembled and properly disinfected. Five resamples were obtained this time; all were negative for Total Coliform and E. Coli. They were also within normal range for chlorine and turbidity.

A weekly analysis for chlorate at the Edmonton water treatment plants from a sample collected December 27th was above the maximum allowable concentration of 1 mg/L as per the Guidelines for Canadian Drinking Water Quality. Re-samples were taken December 27, 28, and 30 from the distribution system and from both water plants. A second set of re-samples were also sent to a third party lab for analyses. It was determined that our internal lab results were in error and that chlorate levels were 0.1 mg/L. The cause of the internal lab error was instrumentation that was not fully conditioned after undergoing scheduled maintenance.

2.6 Production Summary
*Note: beginning in 2015 regional customer population reporting is standardized. The method is to use the census year (2011, 2016...) as a base, then apply a growth factor to subsequent years and round to the nearest thousand. 2013, 2012, and 2011 will be corrected to follow this method. 2009 will be changed back to the original reported value.
